She then went on to complete her nursing degree and graduate training at the MGH Institute of Health Professions.

While attending graduate school, Tessa worked as a psychiatric nurse for Monte Nido, a multi-state eating disorder treatment center. Following graduate school, she gained experience as a Psychiatric-Mental Health Nurse Practitioner at LightHeart Mental Health.

She provides collaborative, trauma-informed behavioral health care for children and adolescents, creating a welcoming space where patients and families feel heard and supported. Her approach is guided by compassion, respect, and partnership, with treatment plans tailored to each child’s unique needs and goals.
